我没有亲身经历过这种情况，但这是一个很好的故事(详见我的评论中的解释):

#define MSGTAG_B33R     0x723 /* RIPLVB */

在drivers/net/sunhme.c (Linux内核)中:

/* Welcome to Sun Microsystems, can I take your order please? */
if(!hp->happy_flags & HFLAG_FENABLE)
        return happy_meal_bb_write(hp, tregs, reg, value);

/* Would you like fries with that? */
hme_write32(hp, &tregs->frame,
            (FRAME_WRITE | (hp->paddr << 23) |
             ((reg & 0xff) << 18) | (value & 0xffff)));
while(!(hme_read32(hp, &tregs->frame) & 0x10000) && --tries)
        udelay(20);

/* Anything else? */
if(!tries)
        printk(KERN_ERR "happy meal: Aieee, transceiver MIF write bolixed\n");

/* Fifty-two cents is your change, have a nice day. */

在大学的一次家庭作业中，一位老师特别坚决地要求我们注释代码:

//I wonder if she actually reads these.

当作业被返回时，在注释“是的，我愿意”旁边用红笔写着

catch (Domain.ConcurrencyException)
{
    // somebody changed it between the time we loaded it and now.
    // weird, huh?
}

在OLTP数据库事务的主要触发代码中找到:

-- This line negates the @inverseqty, which is the
-- negative of the @insertedquantity.  This works through the
-- magic of the trigger.  In fact, this code is a lot like
-- the bermuda triangle!
@negquantity = -1 * @inverseqty

下面是一个必须声明的局部变量，只是为了将一个常量传递给库函数:

// This only exists because Scott doesn't know how to use const correctly
